Application flled April 13,1926. Serial No. 101,610.

This invention relates to safes and has for an object to provide a means adapted to give warning if the safe is opened or drilled by burglars.

More specifically speaking the invention has for an object to provide a safe equipped with a pneumatically operated burglar alarm which, by the release of compressed air contained in the walls of the safe causes an alarm to be given, saidair being con tained in adjustable boxes in the said wall. to allow anadjustment of the box after the safe door is closed to form a better protection.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the 'following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

Fig. 1 ot the drawing is a front elevational view o't' a satte having the invention applied thereto.

Fig. 2 is a vertical sectional view taken on the line 2-J of Fig. 1, showing also in the vdiagrainthe different alarm attachments.

Fig. 8 is a horizontal sectional view taken on the line 8-8 of Fig. 1. i

Fig. 4 is a `detail perspective view oi one of the air boxes.4

Referring now to the drawing, the reference numeral 10 indicates the bottom wall of the safe, 11 they top wall, 12 the rear wall, 18 the two side walls, and 14 the door. The walls and door, of the usual hardened steel, are formed oit a number of separate parts fastened togetl'i-er by studs, as indicated at 9, and presenting shallowrecesses 15 which extend substantially the full area thereof', and thus form a hollow construction. In these recesses are located the shallow glass boxes 16, which are adaptedto contain compressed air, and which I thereforeterm air boxes,'these boxes having air passages 17 leading from one to the other to connect them as a unitary element. The air box in the door 14 has at its two side ends, auxiliary air boxes 42, laterally slidable in grooves ink the safe proper, and provided with air connection pipes 44, connecting with the main air box in the said door. The auxiliary boxes 42 are laterally manually vfor holding the alarm circuit open.

movable,when the door 14 is closed, into recesses 13u vformed in the .side walls 13, Vand .it is advisable to constructthese auxiliary,

lever 47, pivoted at 48, and vprovided at this point with a square projection 49 to receive a tool for turning purposes.- The other end ot lever 47 is pivotally connected toa lever. 50, asat 51, by an elongated slot connection and lever 5() is pivotally mounted as at 52, and carrying a pin 58 at itsouter end, engaging a vertical slot 54 in the boxes 42. .It .is readily seen that by putting a turning tool 01149, the auxiliary boxes may be moved to inner and outer positions,` by the simultaneous action of pins 45, and 53, acting together in the same directions, .in their respective vertical slots 46, and 5,4, of the said boxes. The auxiliary box in extended positions offer a vbetter target, for burglar-s attempting to drill the safe.

The mainair box in the door 14 is con-- nected with one ot' the air boxes in the sate walls by a suitable conduit 17 which may be provided with rubber'packing elements 17a at the edge of the door. l

From one of theairboxeslt a pipe 18ct. hardened steel leads lto the desired point, such as a watchmans room and connects a supply tank 19 of compressed air. In this pipe is an ordinary two way hand valve 2O and it has also connected thereto a device This device comprises a casing 21 to onel end or' which a branch 22 i'rom the pipe 18 leads.y In this casing lis'inounted by wing screws, a frame 28 between which and casin 21 an elastic sheet 24 is held having a heat 24 at its center. The latter bearing on a spring contact .finger 25 to hold `it from engagement with a second contact finger 26.

Suitably mounted in the safein opposition to be engaged by a bridging element 27 on the door when the latter is closed, is a pair vot contact pins 28 and 29 respectively.

- Referring now to .the electric connections,

respectively lead to a three point switch 35 and a bell Set, the wire 30 eonnectiiigl .to that terminal of the switch to which the 'bridging member 35 attached. From a second terminal oit switch 33 a wire 3b' leads to a battery 3T, and from thebatteryBT a wire 3S leads to the bell di.. From the two point:-l ot switch 3B between which the bridging member swings wires d() and 4l lead to the respective contacts 52,8 and 29.

The ymanner of operation and use of my improved burglar alarm tor saltos is as Ytollows: When the alarm is set the parts occupy the position shown in Fiel'. l, conipressed air having' been delivered to the air :boxes liti 'trom the tank 19, the air entering' casing 2l and 'expanding' 'the elastic sheet 24e outward to hold spring contact' 255 awa)y from Contact '26. vrlhe bridging; member 35 of switch 33 is positioned to connect wires '30 and 3G, as =will be apparent, it the sate is tampered with, either to lopen the door 141-. drill anyot the walls thereot, or cut the pipe i8 'the exhaustion ot the air will permit spring' contact 25 to move elastic sheet 24 inwardly-and'engage the Contact thus closing the circuit throunh the bell and niv ing an alarm. The yparty opening the sate in the morning' throws the switch member 35 to Athe position shown in dotted lines which opens the alarm circuit and includes therein'the wires Ll0 and 4l, contacts '28 and 2f), and "bridging piece 27 on the door. Vilfienthe door is closed at night the closing; of the circuit will cause bell 841s 'to ring', notitying vthe watchman to turn on the compressed air which immediately stretches elastic 2st and opens the Acircuit at the contacts 2G and thereupon the bell stops ringing. "Llhe switch member 35 is then returned lto its original position.

TWhile l have illustrated and described my invention, with some degree of particularity, l. realize 'that in practice various alterations therein may be made. l theretore reserve the right and privilege of changing' the torin oli the details o'i" construction or otherwise altering' the arrang'eolent ot the correlated carts without departing 'trom the spirit or the scope o'l" the. appended claims.
